Comfort and Convenience
Power mirrors move the glass itself on small electric motors behind each housing, so the reflected view is set from a switch on the door rather than by pushing the mirror by hand.
Safety and Driver Assistance
The stability program compares steering angle with the car's actual rotation and brakes individual wheels to correct a slide, acting on each wheel separately in a way no driver's hands and feet can.
Multimedia and Connectivity
An AUX input carries analogue sound only, so any player with a headphone socket works, but track names and skip commands stay on the device rather than the car's controls.
